An automotive A/C service typically involves:
✅ Visual Inspection
Inspect A/C compressor, belts, hoses, and connections for leaks or wear.
Check cabin air filter for dirt and debris.
✅ Performance Test
Measure temperature output from vents to see if it’s cooling properly.
✅ Refrigerant Level Check
Check refrigerant levels (often R134a or newer refrigerants like R1234yf).
Low refrigerant = reduced cooling and potential compressor damage.
✅ System Pressure Test
Use gauges to measure high and low pressure in the A/C system.
✅ Leak Detection
Use dye or electronic leak detector to find leaks in lines or components.
✅ Recharging Refrigerant (if needed)
Recover old refrigerant safely.
Recharge with correct amount of refrigerant.
Add oil or dye if required.
✅ Inspect Electrical Components
Check A/C compressor clutch operation and fuses/relays.
🚗 Signs You Might Need an A/C Service
Weak or warm air from vents
Strange noises when A/C is on
Bad smells from vents
A/C cycling on and off frequently
Leaks under the car (could be refrigerant, not just water condensation)
💲 Typical Cost Range
Inspection only: ~$60–$100
Recharge service: ~$159–$275 (varies by refrigerant type and vehicle)
Repairs (compressor, condenser, leaks) can run $300–$1,500+ depending on issues.
